About SMD TCall PMU ESP32 Wireless SIM800L Module Unsoldered
The TTGO T-Call PMU ESP32 Wireless Module is a powerful development board combining an ESP32 microcontroller with a SIM800L 2G/GPRS module for cellular connectivity. This upgraded V1.4 version features the AXP192 power management unit with coulomb counter and high-precision voltage/current testing capabilities. The board is built around the ESP-WROVER-B chip with 8MB PSRAM, providing ample memory for complex IoT applications. It includes a Type-C USB connector for programming and power delivery, along with a Nano SIM card slot and antenna connector for cellular communication. The module supports both WiFi/BLE through the ESP32 and cellular connectivity through SIM800L, making it ideal for remote monitoring, GPS tracking, and data logging applications where dual connectivity is required. The PMU enables efficient battery management with 500mA charging current for 3.7V batteries.
